Performance of air-to-water heat pump using 2 stage vapour injection.

Summary

On the heat pump system, vapour injection (VI) compression cycle's superiority over non-injection cycle has been well known. VI system produces the high heating capacity, and its power consumption is less than the non-injection system. Furthermore, the system design of the vapour compression cycle also minimizes the compressor size. The investigation of VI cycle's influence on the air-to-water heat pump (AWHP) system is presented. At 35°C water temperature, VI AWHP improves 20% heating capacity and 10% COP compared to the conventional AWHP. At 60°C water temperature, VI AWHP improves 48% heating capacity and 12% COP compared to the conventional AWHP. Experimental results are compared at the same compressor displacement volume.
